Description
Technical field：
The present invention relates to bio-filter stuffing technical field, and in particular to one kind prepares bio-filter stuffing using furfural dregs
The method of pore creating material.
Background technology：
Biofilter is a kind of sewage disposal technology, is main treatment with the biomembrane of granulated filler and its apposition growth
Medium, gives full play to the physisorption of biological metabolism, biofiltration, biomembrane and filler particles, collects biological oxidation process
With separation of solid and liquid in one so that the removal of BOD, COD, the filtering of SS and nitrifying process can be in same unitary reactors
Complete, and if increasing anaerobic zone in BAF, can also simultaneously carry out denitrification denitrogenation and dephosphorization.Filler is made
It is the core component of BAF, there is directly influence on effect of BAF.
Pore creating material, is the important component for preparing bio-filter stuffing.Patent CN 102531157 discloses a kind of aeration life
Thing filter tank filler, wherein with sawdust, stalk, leaf as pore creating material, by the discarded object and residue as resources of agricultural product, reducing ring
Pollute in border.
Furfural dregs, are that biomass class material such as corncob, cornstalk, rice husk, cotton seed hulls and agricultural byproducts processing are got a foothold
In material poly-pentose composition hydrolysis production furfural produce biomass class discarded object, with salt content it is high, in acidity the characteristics of,
Its bulk deposition can produce pollution to air, soil, river.Furfural dregs contain substantial amounts of fibre as a kind of biomass class discarded object
Dimension element, hemicellulose, lignin, with good recycle value.Therefore, reasonably recycling furfural dregs, eliminate it
Pollution to environment, while increasing the economic value added of furfural dregs, realizes the zero release of pollutant in furfural enterprise production process
Target, the purpose for reach clean manufacturing, recycling is the problem of furfural dregs recycling urgent need to resolve.
For above-mentioned situation, our company develops a kind of method that utilization furfural dregs prepare bio-filter stuffing pore creating material,
The pore creating material of excellent performance is obtained while realizing that furfural dregs are rationally recycled, and biological filter is prepared using made pore creating material
Pond filler, makes obtained filler have high absorption property to the pollutant in sewage, so as to reduce pollution of the sewage to environment.
The content of the invention：
The technical problems to be solved by the invention are a kind of excellent performance of offer, cost input is low and is conducive to protection ring
The method that the utilization furfural dregs in border prepare bio-filter stuffing pore creating material.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of method that utilization furfural dregs prepare bio-filter stuffing pore creating material, comprises the following steps：
(1) primary drying：Furfural dregs are placed on 270-325 eye mesh screens, and are hung down from screen cloth top using 40-45 DEG C of hot blast
Straight wind, 60-65 DEG C of hot blast of being converted after furfural dregs water content is reduced to 20-25%, until furfural dregs water content is reduced to 3-
5%, obtain final product through the furfural dregs after primary drying；
(2) once wash：To be added in 2-3 times of weight portion water through the furfural dregs after primary drying, 5-8h stood after submergence,
Tea seed cake powder and pre-gelatinized starch are added, 60-65 DEG C of insulated and stirred 15-30min is warming up to the programming rate of 5 DEG C/min, so
After naturally cool to room temperature, cross 270-325 mesh sieves, rinsed with flowing water during sieving, obtain final product the furfural after once washing
Slag；
(3) secondary washing：By after once washing furfural dregs add 2-3 times of weight portion water in, and add pine needle meal and
Polyvinylpyrrolidone, reflux state insulated and stirred 10-15min is warming up to the programming rate of 10 DEG C/min, then naturally cold
But to room temperature, 270-325 mesh sieves are crossed, is rinsed with flowing water during sieving, obtained final product through the furfural dregs after secondary washing；
(4) redrying：In through the furfural dregs feeding freeze drier after secondary washing, dry to water content and be reduced to
15-20%, then size-reduced machine is made the powder of fineness 2-3mm, is subsequently placed on 270-325 eye mesh screens, using 55-60 DEG C of hot blast
From screen cloth upper vertical air intake, until furfural dregs water content is reduced to 2-3%, obtain final product through the furfural dregs after redrying；
(5) once powder processed：To through in the furfural dregs after redrying add volcanic ash and PAMC, fully
Sent into after mixing in ball mill, be milled to fineness less than 50 μm, obtain final product furfural dregs powder；
(6) modification：To addition HPMA, aromatic modified terpene resin and N- phenyl in furfural dregs powder
Maleimide, is warming up to 120-125 DEG C of insulated and stirred 15-30min, in 0-5 DEG C of environment with the programming rate of 5 DEG C/min
0.5-1h is stood, continuation is warming up to 120-125 DEG C of insulated and stirred 10-15min with the programming rate of 5 DEG C/min, then naturally cold
But to room temperature, modified furfural residue is obtained final product；
(7) secondary powder processed：Modified furfural residue is made micro mist of the fineness less than 10 μm through micronizer, most afterwards through nanometer
Grinder is made nanometer powder.
The furfural dregs through after primary drying and tea seed cake powder, pre-gelatinized starch, pine needle meal and polyvinylpyrrolidone
Quality amount ratio is 45-50:0.5-1:0.5-1:0.3-0.5:0.3-0.5.
The furfural dregs through after redrying are 45-50 with the quality amount ratio of volcanic ash, PAMC:
0.5-1:0.3-0.5。
The matter of the furfural dregs powder, HPMA, aromatic modified terpene resin and N-phenylmaleimide
Amount amount ratio is 45-50:0.5-1:0.3-0.5:0.1-0.3.
The beneficial effects of the invention are as follows：The present invention is in tea seed cake powder, pre-gelatinized starch, pine needle meal and polyvinylpyrrolidone
Under assistance, the salt content and acidity of furfural dregs are effectively reduced by secondary washing；Again in volcanic ash, PAMC
Assistance under, furfural dregs are made the uniform powder of fineness；And in HPMA, aromatic modified terpene resin and N- benzene
The modification of base maleimide, increases the specific surface area and adsorptivity of furfural dregs, so as to be beneficial to be improved as pore creating material
Disposal ability of the made bio-filter stuffing to dirty water pollutant.
